Alternatives to Proofide

I know you can ruin a Brooks with a single application of neatsfoot oil because i've done it. I did it many years ago, but i've just dug that saddle out of the box of old bits it was living in, and while not exactly floppy, it is still flexing in ways it shouldn't (the sides flap out when you put any weight on it, and tightening doesn't seem to help).

punch some holes and lace it.
